mechanism and constitutes an improvement upon the spout mechanism covered by my patent issued June 3, 1941, and having Patent No. 2,243,840L" One object of this invention is to provide mechanism by means of which a spout for a grain elevator may be swung in a circular path and brought to a stop in position for-delivering grain to a selected one of the bins oi the elevator, the mechanism being driven by an .electricmoto'r and including as one of its elements a latch actuated by a solenoid which is in series with the motor so that when the motor is started the latch will be drawn to a releasing position and the solenoid de-energised when the motor is shut off so that it may secure the spout in a stationary position in registry with the inlet of a predetermined bin.

Another object of the invention is to provide a distributor spout mechanism having the motor and a gear casing mounted upon a bracket carrying the wheels which travel along a circular track extending parallel to the entrances of bins in a grain elevator.

Another object of the invention is to provide actuating mechanism wherein the motor and the solenoid for the latch may be controlled from a switch board located at a convenient point and the spout caused to move to a position for communicating with a predetermined bin by operating a selected switch of the switch board.

Another object of the invention is to provide an actuating mechanism for a distributing spout of a grain elevator which is compact and of simple and inexpensive construction.

The invention is illustrated in the accompaying drawings wherein:

Fig. 1 is a view in elevation of a distributing spout provided with the improved actuating mechanism.

Fig. 2 is an enlarged view showing the actuating mechanism in elevation and the spout in section.

Fig. 3 is a sectional view taken horizontally through the actuating mechanism along the line 3-3 of Figure 4.

Fig. 4 is a rear view of the actuating mechanism.

Fig. 5 is a wiring diagram.

This improved actuating mechanism for a distributing spout is employed as means for moving a spout into position for communicating with a predetermined bin of a grain elevator which may be of any height and construction desired and has its bins so arranged that their inlets extend in a circular path. The grain flows from 1 Claim. (Cl. E i -118) ahopper I into the upper end .of the spout2 which pivotally mounted by a post 3 and its lower end visprovided with an elbow or nozzle jtwhic'h is downwardly, curved jso that wheng'this nozzle is over the inlet 5' of a: bin grainmay fiowfrom the "spout into the bin. Afcircular'track 16 is mounted upon the floor or platform 'I- through which the; inlets of the bin project; the inlets of the bins being arranged in a circular path-extending about and in concentric relation to the track. J

A block 8 Whichis formed integral with the upper end portion of thenozzle extends downwardly therefrom and has a depending arm 9' to which a bracket I0 is secured. The bracket has side extensions or arms II opposite which are the side portions I2 and I3'of a plate I4, the plate being secured against the bracket by bolts I5 which also secure the bracket to the arm 9 of the block 8. Wheels I6 and I! are rotatably mounted between the side portions of the bracket and the plate by axles or shafts I8 and I9 and these wheels rest upon the track 6 along which they move when the spout is being swung from one bin to another. The shaft I9 extends into a gear housing 20 which is secured against the side portion I3 of the plate I4 by bolts 2| and within the housing or casing carries a gear 22 held fixed to the shaft by a set screw 23. An electric motor 24 is secured to the gear casing 20 by bolts 25 and the shaft 26 projects into the casing and carries a gear 21 which is fixed to the motor shaft by a pin 28 and meshes with the gear 22. The gear 21 is smaller than the gear 22 so that the shaft I 9 is rotated at reduced speed and the spout swung easily from the inlet of one bin to another.

A block 29 projects from the outer or rear face of the plate I4 and is formed with a vertically extending groove or recess 30 which serves as a seat for a plunger or latch 3|. The latch or plunger has its upper portion reduced to form a shank or stem 32 projecting upwardly through an opening at the top of the recess 30 and a spring 33 is coiled about the shank and urges the plunger downwardly so that its lower end portion normally protrudes from the bottom of the block. A plate 34 which is held to the block by screws 35 closes the outer side of the recess and prevents dislodgement or the plunger. A keeper 36 is located opposite the entrance neck of each bin and each keeper consists of a plate which rests upon the floor or shelf 7 and is provided along one side edge with an upstanding flange 31 through which bolts 38 are passed to secure the flange against the confronting side face of the track 6.

A rib 39 projects upwardly from the base plate of the keeper and since this rib has sloping upper edge faces 40 between which is a notch or seat 41 the lower end of the plunger 31 may ride along an upper edge portion of the rib and engage in the notch to stop movement of the spout and hold it stationary with its nozzle aligned with the entrance of one bin. A solenoid 42 is secured against the outer side face of the plate M by screws 43 and the lower end of its core 44 is con nected with the upper end of the plunger 3| by a bolt 45. The coil of the solenoid is connected in series with the motor 24 by the conductor 45 and the motor set in motion. Therefore the.

wheel I! will be driven and the spout swung in a circular path along the track 5 out of registra tion with the inlet of a bin with which it has been in position to deliver grain. The switch 41 is one of anumber of such switches on a board 48 corresponding to the number of bins and each switchhas jassociatedlwith it an automatic cutout of conventional construction for shutting off the-motor as the nozzle approaches the inlet neck of a predetermined bin and the spout will coast along the track with the plunger in its extended position until the lower-end of the plunger rides along a sloping upper edge 40 of the flange or .rib 3 9 and enters the notch 4| to hold the spout against the further movement. In Figure 5 there has been shown a switch board .designed vfor twelve switches, it being assumed that. the elevator'has twelve bins, and it will be understood that each of the twelve switches is hooked into the circuit and is companion to one of the bins and the companion keeper. When it is desired to have the spout move to a certain bin it is merely necessary to close the switch companion 4 to this bin and the spout will be swung about the post 3 and moved along the track 6 until the bin is reached. The switch will then be opened and movement of the spout stopped by engagement of the plunger in the notch 4| of the keeper.

Having thus described the invention, what is claimed is:

Mechanism for moving a spout along an arcuate track from one position to another comprising a bracket adapted' to be, mounted Vertically under 'a spout and supported'against tipping movement thereby, a plate detachably carried by said bracket and having angularly extending side portions, side portions on said bracket and in spaced parallel relation to the first named side portions, wheels between companion side portions and mounted on shafts carried by said side portions. said wheels being positioned adapting them to rest upon the arcuate track, a transmission housing carried by said plate, said housing supporting .a reversible power unit having a rotatable shaft extending into said housing, one of said wheel shafts extending into said housing, and. power transmitting mechanismuniting said power unit shaft-and said Wheel shaft.
